7. Car Confi guration
WARNING
The IIDTool allows changes to vehicle settings to a state outside of
the original manufacturer specifi cation. It is the sole responsibility
of the user to choose secure settings for the applicable use of the
vehicle.
Defi nition
The car confi guration menu allows users to make changes, improve or upgrade software functions
supported by the vehicle. For example:
•
Someone who installs a rear view camera will need to change the confi guration to make it work
in the navigation display.
•
Someone can activate the day time running light options (DRL) on their vehicle.
Note:
Only a limited number of ECUs allow confi guration changes. For a complete list of available car
confi guration options, please consult the functionality list on the product page of our website.

On Range Rover 2005, the ECUs confi gurations are stored using two different methods (CCF and
individual ECU confi guration). On Range Rover 2002-2004, the CCF method is not used.
The
C
ar
C
onfi guration
F
ile, or CCF, contains the confi guration information needed by all systems or
ECUs present in the vehicle connected on the CAN networks. The Instrument Pack broadcasts the
content of the CCF at regular intervals on the CAN networks. Each ECU knows its confi guration and
the confi guration of other ECUs if needed. Other ECUs have a backup of the CCF stored in their
memory and may be used by the vehicle when one copy is corrupted.
Some confi guration are stored inside an individual ECU. When a confi guration is changed, it is pro-
grammed into the corresponding ECU.
